Overview

• Mer Bleue bog in Ottawa was used as a practice bombing range during the Second World War, resulting in unexploded bombs still buried in the area.
• The Department of National Defence confirms that while the exact number of remaining bombs is unknown, historic maps and aerial photographs indicate their locations.
• The National Capital Commission, aware of the site's history, took over the area in 1965 to maintain it as parkland.
• Officials emphasize that the risk to the public is low since the bomb impact areas are deep within the bog and away from public use areas.
• Despite the presence of unexploded ordnance, public activities such as hiking and skiing in the Mer Bleue bog remain unaffected.
